' MOVABLE LOADING-HOPPER.

Specification of Letters Patent.

Application filed January 1914. Serial No. 810,964.

To all whom it may concern Be it known that I, ALBERT P; LEE, a citizenof the United States, residing at Chicago, in the county of Cook andState of Illinois, have invented a certain new and useful Improvement inMovable Loading Hoppers, of which the following is a full. clear.concise, and exact description, reference being had to the accompanyingdrawings, forming a part of this specification.

My inventionrelates to movable loading hoppers and has for its objectthe provision of a new and improved device capable of use for loadingand unloading.

My invention consists primarily of a vehicle having one Or more hoppers,which hoppers are operable to occupy one or an- I other limitingposition, thus to travel preferably from a loading to an unloadingposition.

My invention contemplates in onev of its forms certain features wherebythe hopper may be reversible if desired, so as to change its loading orunloading positions from one to the other side of the vehicle.

My invention in one of its forms also contemplates the provision ofmeans whereby the hopper may be raised or lowered upon the vehicle toaccommodate for proper loading and unloading.

' My invention also contemplates means whereby after the hopper has beenmoved to its unloading position it may be slightly elevated to withdrawthe snout of the hopper from the deposited material.

I will explain my invention more in detail by. referrin to theaccompanying drawings, illustrating the same in which:

Figure 1 is a side view of a vehicle constructed in accordance with myinvention; Fig. 2 is an end view thereof; Fig. 3'is an enlarged detailview illustrating the mechanism for shifting the hopper carryingframework; Fig. 4 is a sectional View. on

lines 'a--aof Fig. 3; Fig. 5 is an end view 'ofthe mechanism providedforhopper reversing purposes, and Fig. 6 is a view partially in sectionillustrating an endelevation oftheystructure' illustrated in Fig. 5. i

Referring more particularly to Fig. 1, I show a vehicle consisting ofthe truck portion I mounted upon suitable wheels 2, 3.

The truck portion is also shown more clearly in Fig. 2 as carrying aplurality of struts 4, 5 and 6 adapted to support a shaft 7. Upon thisshaft 7 a pair-of tilting beams 8 may be.

are mounted, which tilting beams for this J purpose are each providedwith a bearing 9 suitably fastened to said tilting beams. Surmountmg thestruts 4; and 6 are posts 10 which pivotally support a rod or pipe 11.Thls rod is provided at its opposite extremities with a T 12, from whichT pipes or rods 13, 13 extend in opposite directions whose extremitiespivotally rest in sockets 14, 11 provided therefor in the frameworks 15for supporting the hoppers l6 and 17. These frameworks 15, 15 arepivotally connected by shafts 18 mounted in the tilting beams 8, 8. Itwill be seen now that the frameworks 15, being pivotally supported uponthe tilting beams 8 and being also associatedwith the posts 10 by meansof the rods 13, that these frameworks 15 will at all times occupy asubstantially vertical position if the vehicle stands in a horizontalposition. The tilting bars 8 are each provided with a framework 19,which carry at their lower extremity a segmental gear 20 adapted to meshwith pinions 21, 21, which pinions are carried by a shaft 22 supportedin brackets 23 carried by the truck body 1. A shaft 22 also carries aratchet wheel 24: adapted to be engaged by pawls 25 and 26 controllablerespectively by the hand holds 27 and 28 vmounted upon the. rocking bar29, which rocking bar is also pivotally:

mounted upon the shaft 22.. It will be seen thus that by operating thehandle 29 and releasing one or the other of the-pawls, that the shaft 22may be rotated to thereby cause a gradual tilting ofthe tilting beams 8,thus elevating one hopper 16, for instance, and lowering'the .other, orvice versa, as the case agency of rods 32, 32 controlled by handles '34,'34, may be withdrawn from engagement with their ratchetwheels 30. Thepurpose of these ratchet wheels. 30 is to hold the gear wheels 21 in anyposition set so that the tilting bars 8 maintain whatever positionisgiven to them through the actuation of the actuating lever 29. Whenboth pawls 31 are in engagement with the teeth of their respectiveratchets 30, then of course the shaft 22 is locked against rotation ineither The shaft 22 also carries a pair. of ratchetsi30 adapted to beengaged by the 'pawls 31, 31 respectively, which through the adapted toroll, these hoppers being provided with channels 36 for that purpose.

Referring more particularly to Fig. 2, it will be seen that these railsterminate in fingers 37 adapted to engage pins 38 mounted upon thehoppers 17 to prevent the hoppers from entirely leaving the rails whenthese hoppers are moved into them limiting positions for unloading, asshown more clearly in Fig. 2. The hopper shown in full lines in Fig. 2is supposed to be in the loading osition. When in this posltlon thehopper 1s held by means of chains 39, shown more clearly in Fig. 1,which chains are held in place by fingers 40, to thus prevent the hopper17 of Fig. 2 from rollin to the right. When the hopper is fille then thefinger 40 is released from its engagement with the chains 39, whereuponthe hopper either due to its own over-balanced condition, or with thehelp of a slight push, rolls into the position shown in dotted lines inFig. 2, to be held by the fingers 37 and the chains 70. Chains 42, 42are provided to limit the upward and downward movement of the rockingbars 8. In order to actuate the fingers 40 it may be stated that thesefingers form part of arms 42, which arms are pivoted at 43. These armsare linked to a further arm 44 under the control of a lever 45 pivotedat 46. Now whenever the right hand lever 45 of Fig. 1, for instance, ismoved in a contra-clockwise direction, it naturally moves the arm 42 ina contraclockwise direction about its pivot 43, thus elevating thefinger 40 and permitting the chains 39 to slide away from engagementwith said finger 40. As has already been stated, the hoppers are soconstructed that they roll either of their own initiatlve from theloading to the unloading position.

Now it may be desirable instead of havmg the loading position to theleft of the vehicle, as shown in Fig. 2, to have the loading positionto' the right of the vehicle. In order to accomplish this, I reverse theposition of the hopper 17 upon the rails and this 1s done by means ofthe trough 47 pivotally carried upon a screw threaded stud 48, whichfinds screw threaded'engagement with the screw threaded socket 49. Thissocket is carried by the shaft 18 and thestud 48 travels loosely throughthe bridge 50. The stud 48 has a collar 51 provided with an aperture 52so that when a bar is inserted into this aperture the stud 48 may berotated to elevate the trough 47, which thereupon engages the hopper 17and thereupon lifts the same clear of the rails 34, 35. Under theseconditions the hopper 17 and the trough 47 may be rotated about the stud48 into the reverse position, at which time the stud may be againlowered to permit the hopper to rest upon the rails 34, 35. During thisreversal, of course, the chains must be loosened and at- 'hopper whendischarging. From what has been described it is thought the nature ofthls stationary loading mechanism will also be apparent.

Haying however thus described my invent1on, it will be clear that it issusceptible of many and variousmodifications without departing from itsspirit.

Having however thus described one form which my invention may take, whatI claim as new and desire to secure by Letters Patent 1s:
